Description


Secunia Research has discovered a vulnerability in the Opera browser, which can be exploited by malicious people to fake (spoof) information displayed in the address bar.

The vulnerability is caused due to the Opera browser changing information in the address bar as soon as the browser is "asked" to redirect to a new page. However, using e.g. the <BODY> tag attribute "onUnload", it is possible to abort the redirection without the address bar being changed back.

This can be exploited by a malicious website to trick users into thinking that they're on another website.

The vulnerability has been confirmed in version 7.23 for Windows and Linux. Prior versions may also be affected.


Solution:
Update to version 7.50.
